The Beatles album Sgt. Pepper's Lonely Hearts Club Band already had a cover designed by a Dutch group called The Fool ( they later painted the psychedelic mural on the facade of the Beatles' Apple Boutique in London's Baker Street ) but gallery dealer, Robert Fraser, suggested to Paul McCartney that they use a fine artist to do the cover instead. McCartney rather liked the idea so noted British "pop" artist Peter Blake was asked to design it.
According to Blake, the original concept was to create a scene that showed the Sgt. Pepper band performing in a park; this evolved into its final form, which shows The Beatles, as the Sgt. Pepper band, surrounded by a large group of their heroes, rendered as lifesized cut-out figures.
Most of the suggestions for names to be included came from McCartney, Lennon and Harrison, with additional suggestions from Blake and Fraser. Ringo demurred saying, "Whatever the others say is fine by me."
The collage, which depicted more than 70 famous people, including writers, musicians, film stars and (at Harrison's request) a number of Indian gurus, was assembled by Blake and his wife Jann Haworth during the last two weeks of March 1967 at the London studio of photographer Michael Cooper, who took the cover shots on 30 March 1967 in a three-hour evening session.
